Heat preservation automatic quantitative feeding system for vacuum cold die casting

Abstract

The invention belongs to the field of die casting, and relates to a heat preservation automatic quantitative feeding system for vacuum cold die casting. The heat preservation automatic quantitative feeding system for vacuum cold die casting comprises a heating and heat preservation tank fixedly arranged on the ground, a flow guide plate is fixedly arranged in the middle of the inner side of an inner cavity of the heating and heat preservation tank, and the inner cavity of the heating and heat preservation tank is divided into an upper cavity and a lower cavity by the guide plate. In the production process of a horizontal cold chamber die-casting die, a die-casting system is vacuumized, used solid metal materials are subjected to melting, filtering, heat preservation and storage, molten metal used in the die-casting process is automatically and quantitatively fed, and the problems that a traditional feeding mode is not beneficial to vacuumizing, the feeding efficiency is low, fed materials have impurities, the temperature and the feeding amount are not stable, and product defects and material waste are caused are solved.

Description

technical field [0001] The invention belongs to the field of die casting, and in particular relates to a thermal insulation automatic quantitative feeding system for vacuum cold die casting. Background technique [0002] At present, the cold chamber die-casting machine die-casts high-melting-point metals such as aluminum and steel. The die-casting machine is separated from the furnace body. The feeding port is manually poured with molten metal or mechanically fed with a soup machine. Defects and waste of die-casting materials. Due to the high temperature and high density of the metal soup, the metal liquid is directly in contact with the air to produce metal oxides and residues. The traditional soup feeding method mixes the residues and oxides with the metal soup. Going away, resulting in poor compactness of die castings, defects such as pores and sand holes. Since the die casting machine is separated from the furnace body, each feeding will cause the temperature of the molt...

[0002] At present, the cold chamber die-casting machine die-casts high-melting-point metals such as aluminum and steel. The die-casting machine is separated from the furnace body. The feeding port is manually poured with molten metal or mechanically fed with a soup machine. Defects and waste of die-casting materials. Due to the high temperature and high density of the metal soup, the metal liquid is directly in contact with the air to produce metal oxides and residues. The traditional soup feeding method mixes the residues and oxides with the metal soup. Going away, resulting in poor compactness of the die-casting parts, defects such as pores and sand holes, because the die-casting machine is separated from the furnace body, each feeding will cause the temperature of the molten metal to change, making the molding effect of the die-casting parts poor, and the production requirements of the die-casting parts cannot be accurately guaranteed
